World Trade Center Towers

Since the World Trade Center Towers collapsed in full view of the watching world (FEMA, 2002), the improved safety of tall buildings has become of prime importance globally (Pearson, 2001). International groups such as the UK-based ‘Safety in Tall Buildings Working Group’ (Roberts, 2002), and Arups High Rise (Wainwright, 2002) which are considering these safety implications have made recommendations for improvement in three general areas: structural systems, especially with respect to progressive collapsefire proofing, to structure and fabricevacuation systems, concentrating specifically on vertical evacuation systems such as elevators and stairs.

The Impact

The qualitative analysis for structural robustness study subjected to severe earthquakes is unable to meet engineering requirements, and a quantitative analysis method for structural robustness is needed to be proposed. The existing analysis methods, such as Incremental Dynamic Analysis Method and Pushover method, only study the response of the structure directly from the macroscopic view, rather than focusing on the response of a single component on the structure. Especially for the construction of isolated structure, the impact of accidental bearing failure on the isolated structure and the impact of progressive collapse cannot be considered. In this paper, based on the Alternative Load Path Method, the quantitative analysis method for structural robustness analysis under earthquake is proposed. The structural robustness of some different vertical irregular isolated structures under different earthquakes is studied.

The Moment

The corner joints of the fringe frame are the most vulnerable components among RC frame structural joints when subjected to progressive collapse, but very few research focused on its performance against progressive collapse. In this research, nonlinear static analysis method was used to analyze the vertical resistance of corner joint against progressive collapse by finite element software ANSYS. The influence of structural design parameters were also studied through comparative analysis. The result shows the joint ultimate vertical resistance is mainly influenced by the moment carrying capacity of the beam ends and column ends. Consequently, this research could offer reference for structural design against progressive collapse.
